JACKSONVILLE, Fla. -- Automakers are giving us a sneak peek at cars that drive themselves. We may be getting closer to a car like "Kitt" from the TV series, "Knight Rider."

At this week's Consumer Electronics Show in Las Vegas, a number of automakers introduced driving-assist cars, and for the future, cars that would drive on their own. "New things are happening to make it safer," Rocky Roberts of North Florida Traffic School said.

Roberts has been teaching at North Florida Traffic School for 16 years. He said while these new features could make our lives easier and possibly the roads safer, he has this warning.

"But the downside to that is if it does work and you're in that vehicle it's good, but if you get back into a regular vehicle you don't want to ever forget the fundamental things that you learned in driver's ed and all of that about always being aware of your surroundings," he explained.

So how would you feel driving a car, without your hands on the wheel? Driver Mary Carroll said, "I think that for younger people that are not used to doing things an old way, I think it's fine. I think for older people, it's going to be hard to adjust. And I'm one of the latter."

A lot of these cars have some of the technology on display at the Consumer Electronics Show. But, you will have to wait a bit longer for cars that can drive themselves.
